float level control valve a Needle Valve b Ball Valves c In-line Finger Filter description Armaş “FL” model float level control valve is the hydraulic control valve designed to control water level in reservoirs and tanks continuously. Main valve is controlled by 2-way modulating type float pilot valve manually. Main valve mounted on reservoir and tank upstream is closed as fully sealed without causing surge when water level reaches to maximum level. Valve opening/closing speed may be adjusted in set value. It may be used in the system by mounting horizontal or vertical positions. installation • Make sure that valve is on a level with the pipeline while mounting it. • Mount valve in direction of arrow indicated on it. • While mounting valve on pipeline, place gasket between valve flange and pipe flange to ensure sealing and tighten the bolts as crosswise. • Mount main valve body on tank or reservoir upstream and mount float components in tank or reservoir as fixed in desired level interval. • It is recommended that insulation valves (butterfly or gate valves etc.), air relief valve and strainer valves will be used in linemounting of valve (see sample montage illustration). 1 Isolation Valve (Gate, Butterfly Valve etc.) 2 Modulating Type Float Level Control Valve 4 Float 5 Water Tank

adjustment • Mount float pilot valve indicated with "d"as fixed according to water level in tank or reservoir. • Connect one end of hydraulic pressure signal tube supplied with valve to ball valve indicated with "b2"and other end to float pilot valve. • Open ball valves indicated with"b1"and"b2" • Needle valve indicated with "a" is used for adjusting opening/closing speed adjustment of main valve. maintenance •System operating conditions that effect on the valve should be checked periodically to determent the required preventative maintenance schedule. •Check finger filter indicated with...
